I have to replace the water pump on my B. Is there a trick to getting the front nose cone and grille off? I pulled all the bolts I could find and it will wiggle some, but does not seem to want to come off. Do I need to unhook the radiator hoses and pull the radiator and the shroud off together? I don't want to force something and break it. The bottom of the nose piece below the grille is banged up pretty badly.
